Battery packs are a great accessory to have on hand in case you run out of battery power on your mobile devices, but with a battery pack you want them to just as easily portable as the devices you’re looking to charge. This deal on a Xiaomi portable power bank gives you just that. A slim, fairly lightweight battery pack in a sleek silver color that’s easy to tote around in a bag or a pocket. It carries 16,000mAh of battery capacity so you can charge your device multiple times before you need to recharge the pack itself. It also has 4 LED indicator lights so you can see the status of the battery pack and know when to plug it in, and two USB ports so you can charge two devices at once if you need to.
